Out of focus photo
in [Photoshop Graphics]
|
From: The Old Bloke on 28 Nov 2009 03:39 Hi People, Is there anyway to fix/enhance an out of focus photo? I think the answer is no, but this is a really special case. A Mate of mine lives in a remote part of Australia. His son turned 18 recently and there was a rare family reunion to celebrate the day. The young lad is in a wheelchair, and maybe has another year to live. The family photo was badly ourt of focus. Does anyone have a magic technique? Regards Doug

I'd suggest making the image available and see what some of us can do with it. If privacy is an issue, which it may well be for a family image, perhaps you could email individual copies. Based on past experience, I think the image can be improved over what you have now, using curves, and un-sharp mask to make things somewhat better. On a more experimental (aka probably not practical) note, it *might* be possible to improve your image using a process called de-convolution. Here's a web page demonstrating some relatively recent work in this area. The basic process consists of taking measurements of the camera properties, then using a rather hefty algorithm to reconstruct a blurred image. The Home page includes a link to some free experimental software that was used. http://www.bialith.com/Research/BARclockblur.htm -- Mike Russell - http://www.curvemeister.com

If it's lens blurring caused by a poorly focused camera, you can duplicate the layer in photoshop, run a high pass filter on it and set the resulting layer to "Overlay" blend mode. This will detect and enhance all the edge contrasts in the image. It won't increase the sharpness, but it will give the illusion that it has. If it's motion blur caused by camera movement, there's really not a lot you can do unless you're prepared to do a lot of heavy duty reconstruction using the clone tool. If it's fringeing caused by chromatic abberation, you'll find Photoshop actually has a dedicated tool for fixing this under "Filters>Distort>Lens Corection". Chromatic abberation is identified by coloured fringes around items in the image, usually towards the edges and corners, and the tool corrects it by shunting and resizing the red, green and blue channels. If you could post a link to the picture, we might be able to offer more comprehensive help.
